High spectral resolution time-resolved optical spectroscopy of V893 Sco [PDF]

open access: yes, 2001
We present high resolution time-resolved optical spectra of the high inclination short orbital period dwarf nova V893 Sco. We performed spectral analysis through radial velocity measurements, Doppler mapping, and ratioed Doppler maps.

T½ Tuning in a Synergistic BODIPY‐Tetrazole Fe(II) Spin‐Crossover‐Photoluminescence System via Co‐Ligand Variation

open access: yesChemistry – A European Journal, EarlyView.
We report a modular spin crossover‐photoluminescence (SCO‐PL) system: heteroleptic, mononuclear Fe(II) coordination compounds bearing equatorial BODIPY fluorophores that exhibit synergistic PL response upon spin state switching. Exchanging apical nitrile co‐ligands tunes electronic and structural properties, giving precise control over the SCO and PL ...

Reversible I2 Uptake Induces Record‐High Spin‐Crossover Hysteresis in a Fe(II) Hofmann‐Type MOF

open access: yesChemistry – A European Journal, EarlyView.
Reversible iodine uptake in a flexible Fe(II) Hofmann‐type MOF [Fe(pz)Pd(CN)4] induces record‐wide SCO hysteresis. Gas‐phase I2 acts as internal chemical pressure, stabilizing both high‐spin and LS states without altering the framework, providing a general strategy for tunable bistability in coordination networks.

New members of the TW Hydrae Association and two accreting M-dwarfs in Scorpius-Centaurus

open access: yes, 2015
We report the serendipitous discovery of several young mid-M stars found during a search for new members of the 30-40 Myr-old Octans Association. Only one of the stars may be considered a possible Octans(-Near) member.

Sudan at War With Itself: Civilian Devastation in the Civil War

open access: yesConflict Resolution Quarterly, EarlyView.
ABSTRACT A civil war is raging in Sudan between the Sudan Armed Forces (SAF) and the Rapid Support Forces (RSF) along with militia groups. Beginning on April 15, 2023, and continuing at least to this writing (October 15, 2025), civilian noncombatants have been subjected to bombings, beatings, torture, shootings, rape, and murder on a large scale. Since

Classroom boundaries and teacher agency: Challenges of implementing Ireland's new primary curriculum

open access: yesThe Curriculum Journal, EarlyView.
Abstract This article reports on a doctoral study examining teacher agency in one Irish primary school at a timely moment ahead of the implementation of the new Primary Curriculum Framework in September 2025. The framework embeds teacher agency as a central professional principle, yet findings from this study reveal a more cautious and bounded reality.

Implementation of the frequency-modulated sideband search method for gravitational waves from low mass X-ray binaries

open access: yes, 2013
We describe the practical implementation of the sideband search, a search for periodic gravitational waves from neutron stars in binary systems. The orbital motion of the source in its binary system causes frequency-modulation in the combination of ...

Social Comparison and Its Association With Disordered Eating Symptoms: A Systematic Review and Meta‐Analysis

open access: yesInternational Journal of Eating Disorders, EarlyView.
ABSTRACT Objective Social comparison has been widely implicated in the etiology and maintenance of body dissatisfaction and eating disorders. At the same time, however, the magnitude of this relationship remains unclear, with existing studies varying widely in methodology, measurement, and sample characteristics.
